TShark作为wireshark的命令行工具。
TShark 是一个网络协议分析器。可以进行实时网络捕获数据包数据，或从以前保存的捕获文档中读取数据包，将这些数据包的解码形式打印到标准输出或将数据包写入文档。TShark的原生捕获文档格式是pcapng格式，这也是Wireshark和其他各种工具使用的格式。
如果不设置任何选项，Tshark 将像 tcpdump 一样使用 pcap 库从第一个可用网络接口捕获流量，并在标准输出上为每个接收的数据包显示摘要行。
TShark 捕获网络流量，通过-i选项参数指定网卡
cd “D:\Program Files\Wireshark”
.\tshark.exe -i "以太网 4" -w c:\20230101_.pcapng Ctrl+C 结束抓包
TShark 捕获网络流量，通过-i选项参数指定网卡
.\tshark.exe -i "以太网 4" -T fields -e tcp -w c:\20230101_01.pcapng
TShark 捕获网络流量，通过-f选项过滤网络流量
.\tshark.exe -i "以太网 4" -f "host 172.20.10.3" -w c:\20230101_01.pcapng

-H <hosts file> read a list of entries from a hosts file, which will
then be written to a capture file. (Implies -W n)

(or '-' for stdout)
--capture-comment <comment>
add a capture file comment, if supported
-C <config profile> start with specified configuration profile
-F <output file type> set the output file type, default is pcapng
an empty "-F" option will list the file types
